Wearable sensors are portable measurement tools that are becoming increasingly popular for the measurement of joint angle in the upper limb. With many brands emerging on the market, each with variations in hardware and protocols, evidence to inform selection and application is needed. Therefore, the objectives of this review were related to the use of wearable sensors to calculate upper limb joint angle. We aimed to describe (i) the characteristics of commercial and custom wearable sensors, (ii) the populations for whom researchers have adopted wearable sensors, and (iii) their established psychometric properties. A systematic review of literature was undertaken using the following data bases: MEDLINE, EMBASE, CINAHL, Web of Science, SPORTDiscus, IEEE, and Scopus. Studies were eligible if they met the following criteria: (i) involved humans and/or robotic devices, (ii) involved the application or simulation of wearable sensors on the upper limb, and (iii) calculated a joint angle. Of 2191 records identified, 66 met the inclusion criteria. Eight studies compared wearable sensors to a robotic device and 22 studies compared to a motion analysis system. Commercial (n = 13) and custom (n = 7) wearable sensors were identified, each with variations in placement, calibration methods, and fusion algorithms, which were demonstrated to influence accuracy. Wearable sensors have potential as viable instruments for measurement of joint angle in the upper limb during active movement. Currently, customised application (i.e. calibration and angle calculation methods) is required to achieve sufficient accuracy (error <  5°). Additional research and standardisation is required to guide clinical application. This systematic review was registered with PROSPERO (

Measurement of Upper Limb Range of Motion Using Wearable Sensors: A Systematic Review

Emotional design for digital games for learning: The effect of expression, color, shape, and dimensionality on the affective quality of game characters

As a proactive risk management instrument, failure mode and effect analysis (FMEA) has been broadly utilized to recognize, evaluate and eliminate failure modes of products, processes, systems and services. Nevertheless, the conventional FMEA method suffers from many important deficiencies when used in the real world. First, crisp numbers are adopted to describe the risk of failure modes; but, in many practical situations, it is difficult to obtain exact assessment values due to inherent vagueness in the human judgments. Second, the priority ranking of failure modes is determined based on the risk priority number (RPN), which is questionable and strongly sensitive to the variation of risk factor ratings. Therefore, this paper applies linguistic distribution assessments to represent FMEA team members’ risk evaluation information and employs an improved TODIM (an acronym in Portuguese of interactive and multicriteria decision making) method to determine the risk priority of failure modes. Furthermore, both subjective weights and objective weights of risk factors are taken into account while conducting the risk analysis process. Finally, an empirical case concerning the risk evaluation of a grinding wheel system is presented to demonstrate the practicality and effectiveness of the proposed new FMEA model.

Emotional recognition is a groundbreaking technique currently used in research where it is necessary to evaluate the emotional reaction of an individual with respect to the content which is being exposed, thanks to advances in electronic devices and computing this technique is used in different fields as an interdisciplinary study.Physiological signals as emotive response and video games as a tool for stimulating these emotional responses, allows in an effective manner the recognition of emotional state carrying the individual to express these emotions through physiological changes emulating situations through virtual environments with which can interact.

This article presents the design of a technological platform called MedicHand, composed of a functional prototype of an electronic bracelet, and web system, elements which, together, allow for control the supply of medication to people who suffer from diabetes. In the first part, the problem Diabetes Mellitus (DM) for the immune system is discussed, as well as the situation of the medical treatments associated with this disease and the current medical trends. In the same way, the technologies involved in the construction of the device, the components that integrate the technological platform, the communication protocol and the design of the bracelet are described.

Technological Platform for the Control of the Medication Supply to People with Diabetes

The use of soft and flexible materials in rehabilitation support systems based on robotic exoskeletons plays a crucial role in ergonomics, reducing weight and complexity. However, the selection of these materials can have mechanical implications that affect the performance of the exoskeleton in the chosen application. This paper proposes a testing protocol to assess the mechanical and structural features of a prototype upper limb robotic exoskeleton using an optical motion capture system as the primary measurement instrument. In addition to the protocol, a literature review is presented, laying the ground for the theoretical development of the mechanical evaluation for prototypes. Also, the materials used concerning the evaluation technologies required for data collection and assessment of the devices are described. The development and future application of this protocol will enable the identification of the relevant motion parameters on the exoskeleton prototype, the changes that its structure may experience due to the use of the flexible materials, and the effectiveness of the mechanical support provided in the upper limb. Finally, the proposed protocol can be extended to other types of robotic exoskeletons built with similar materials, regardless of their final application, extending its applicability to other study cases.

Protocol Proposal for the Mechanical Evaluation of a Soft Robotic Exoskeleton Using an Optical Motion Capture System

Mechatronic systems that allow motorized activation in robotic exoskeletons have evolved according to their specific applications and the characteristics of the actuation system, including parameters such as size, mechanical properties, efficiency, and power draw. Additionally, different control strategies and methods could be implemented in various electronic devices to improve the performance and usability of these devices, which is desirable in any application. This paper proposes the integration and testing of a high-torque, servo-driven joint and its electronic controller, exposing its use in a robotic exoskeleton prototype as a case study. Following a brief background review, the development and implementation of the proposal are presented, allowing the control of the servo-driven joint in terms of torque, rotational velocity, and position through a straightforward, closed-loop control architecture. Additionally, the stability and performance of the servo-driven joint were assessed with and without load. In conclusion and based on the obtained results, the servo-driven joint and its control system demonstrate consistent performance under the proposed test protocol (max values: angular velocity 97 °/s, torque 33 Nm, positioning RMSE 1.46°), enabling this approach for use in various applications related to robotic exoskeletons, including human performance enhancement, rehabilitation, or support for daily living activities.

Physical rehabilitation refers to the recovery of human capacity for the autonomous performance of daily activities based on an evaluation and treatment leading to minimizing problems in neuromotor function. This is a process that takes time, constant support and the making of appropriate decisions by health professionals, but above all the motivation of the patient. To this end, the architecture of a web platform integrated with serious videogames and a motion capture system to support the process of musculoskeletal rehabilitation is proposed. A review of the literature with therapeutic proposals for the rehabilitation of the upper limb using videogames and motion capture systems is presented. The results obtained showed that some works focus on the use of Kinect as a motion capture system; others are commercial systems; and other proposals explore the advantages of inertial measurement units. Regarding the use of videogames, the works reaffirm the significant contribution that they make in rehabilitation processes of the neuromotor system. Taking the above into consideration, an architecture for a telerehabilitation platform is proposed as a motivating alternative, which offers precise physiotherapeutic information in real time, as an attempt to help accelerating recovery time of patients.
